Windows: Description and Operation

Function Of Safety Power Window

When driver door power window auto-up switch is operated, safety function is activated.
1. Safety function condition
When detect the force of 100N (using the 10N/mm spring) during the window rising, window is reversed.
2. Length of window reversing (except holding the auto-up switch)
A. When detect the jamming during the 4mm ~ 250mm from top of the door.
-> Window is reversed until 300mm from top of the door.




B. When detect the jamming over the 250mm from top of the door.
-> Window is reversed until 20mm from jamming position.




3. Length of window reversing (holding the auto-up switch)
A. When detect the jamming during holding the auto-up switch.
-> Window is reverse until 25mm from jamming position.
B. Auto-up function is not available during the 5 seconds from above condition.
-> When holding the auto-up switch, window is operated as a manual-up function. (Safety function is not activated.)
C. When holding the auto-up switch after 5 seconds from above condition.
-> Window is reverse until 25mm from jamming position.




4. Safety function is not available area
Safety function is not available during the 4mm from top of the door.

Initializing Method Of The Safety Power Window
1. Initializing of Battery Connection
When the window cannot be properly closed or opened, safety power window switch need the initializing.
(1) Power window operation before initializing
A. Manual-Down function is not available
(2) Turn the ignition switch to the ON position.
(3) Push down the power window switch until the window glass is entirely down.
(4) Turn the ignition switch from OFF to ON within 2 sec.
(5) Push down the power window switch three times continuously within 5 sec.

Reinitializing Method
1. Close the power window.
2. Push up the power window switch to the close position for 1 sec.

Short Drop
The short drop (SD) functionality is linked to the door ajar signal. In case of door opened, the door ajar signal (low level) will be received by the ECU. As a result the upper stop position will be changed from upper mechanical block position to the short drop position (EEPROM parameter). Short drop commandos will be executed independent of multi function line state.
